PROBLEM TO BE SOLVED: To obtain a mechanism for changing the movement of a puck in an air hockey game machine from the monotonous one into the one to be varied in a progressing direction, and to achieve posterior attachment/detachment. SOLUTION: A projected pillar is attached onto an air hockey playing field 1. When the puck 3 hits the projecting pillar 2, the progressing direction of the puck 3 is changed. According to selection of material for the projecting pillar 2, the repulsive angle of the puck 3 differs, so as to hardly predict the direction after the hitting. The projected pillar is attached with tapping screws 9 through the use of air holes 4 on the field 1. COPYRIGHT: (C)2007,JPO&INPIT
